For this lab, you will be given a plastic bag full of cation tiles (pieces of paper) and another bag full of anion tiles. The cation tile have a wedge or cut-in triangle removed from it for every 1 positive charge on the ion (for example, aluminum ion would have 3 wedges removed from its tile). Anion tiles have a wedge or triangle added to its tile, again for every 1 negative charge (for example, sulfate ion would have 2 wedges added).
Objective
You will make as many correct chemical compounds as you can with the tiles you are given. At a minimum, you will need to make 10 compounds of each of the 3 types of ionic compounds (Naming Binary Ionic Compounds, Naming Ionic Compounds with Polyatomic Ions and Naming Ionic Compounds with Cation with more than one charge). Therefore, it is a minimum of 30 compounds you will need to make.
The ion pieces can found at [Ion Pieces for Naming Ionic Compounds] or will be available in class.
Directions / Procedures:
1. You will pick a cation and an anion.
2. Write down the symbol and charge of each ion in the order it will go in the ionic compound.
3a. From the "in" wedges and "out" wedges, you put down as many ion of each you need so that all the wedges match up.
3b. Actually draw the wedges in your lab notebook so show you have as many as you need.
4. Then add up how many of cation tiles you have. Then you write down the cation name and the subscript is the number of cation tiles. No charges are used.
5a. Repeat step 4 for the anion making sure to put it next to information from Step 4 to make the correct chemical compound.
5b. Check to see if you need parentheses on any of the ions (as you remember parentheses are used for polyatomic ions).
6. Then name the ionic compounds using the rules/direction stated in the Naming Ionic Compounds webpages.
7. Repeat Step 1 thru Step 6 for all compounds.
